Marathon of errors opening game

[thecameronator]

So, I haven't been able to open Doom Eternal at all yet. At first, I was greeted with a message telling me "no graphic devices found" or something like that. After some digging I learned that this was a fairly common Vulkan-related problem when you have multiple GPUs. But I only have one dedicated GPU, no integrated GPU - just an Nvidia GeForce GTX 560M 3GB (yeah yeah, I know. A bit low end for this game, but it manages to run Doom 2016 just fine at around 50-60fps so I thought it would at least be able to squeeze out some minimum quality gameplay for Eternal).

Anyway, I got the new Nvidia update, downloaded the Vulkan SDK, and that kind of helped. In that now I receive a different error message. Now it's "could not enumerate graphics devices". I haven't found a lot of info on how to combat this error, so I tried to bypass the ID Tech Launcher and run the game straight from the Doom Eternal exe, and got yet another error message. This time at least with some details - "the procedure entry point vkGetPhysicalDeviceFeatures2 could not be located in the dynamic link library vulkan-1.dll"

What can I do?? I'm too well versed in coding, but I can at least follow a step-by-step procedure if anyone has something for me.

To summarize:
- Drivers are up to date with the latest Nvidia update
- I don't have multiple GPUs
- The one I have is a bit out of date, but it should manage (just)
- Downloaded Vulkan SDK
- "Could not enumerate graphics devices" error message when launching via Steam/ID Tech Launcher
- "the procedure entry point vkGetPhysicalDeviceFeatures2 could not be located in the dynamic link library vulkan-1.dll" error message when trying to launch directly from Doom Eternal exe

Help plz!

PS you can berate me for trying to run this thing on old hardware, but try to make it useful.

Cheeky bump - still haven't solved it.

Would love to hear someone help you here I'm on a 560ti and wanna give it a shot (LowSpec Gamer has managed some stuff so it's possible) you had any luck?

bump same issue

Oh darn, sorry it turns out those cards aren't Vulkan supported and there is no OpenGl support (Or directX) I spent awhile looking for ways around it but I couldn't find any. A real pain since LowSpec Gamer can get it working on integrated but with no Vulkan drivers there's no real way to run it.

Unless someone else creates a vulkan driver for earlier models but that's above my paygrade

The fact that I had it working on launch and played about 6 hours on my 970m laptop is proof enough that it works and the issue of it stopping to work whatsoever is something wrong with the game itself

Alas a 970m is Vulkan supported, 500 series are not. (Not saying that it's right or anything Nvidia arbitrarily drew a line where they'd not support Vulkan).

Ah double edit, just realising things, so yours is not launching now on a 970m that it worked on before? With the same error as above?

I fixed the above error by getting the Vulkan api but now I am stuck back with the "Failed to allocate memory" problem (first problem that popped up and I've been trying to fix it.... for almost a week now)

Hm only issue I can think of is it's trying to run off your integrated card as opposed to the dedicated? Beyond that don't think I'm much help

there is no other card...

FYI... If you're on Windows 10 sometimes it installs the PnP Generic Driver along with your actual GPU ... To fix go to device manager, display adapter and disable the integrated generic driver... then reboot and see if it finds your video card now.

Another thing you can try is to navigate to the Steam Folder where the DoomEternalx64vk.exe is located and right click on it, then click properties: go to second tab Compatibility and run the compatibility Troubleshooter and see what it tells you. Sometimes it can be a simple allocation of memory problem, or something else that you can change right there on that screen. Just a suggestion...
